WINDOW-LIFT.

To all whom it may concern:

Be it known that I, WILLIAM J. Hnsrnn, a citizen of the United States,residing at Portland, in the county of Multno-mah and State of Oregon,have invented certain new and useful Improvements in Window-Lifts, ofwhich the following is a specification.

This invention relates to windows, and more particularly to a windowhaving a window sash mounted therein, adapted to be raised slightly, sothat it will clear the window sill, and then swung upon supportinghinges, at one side thereof, in the manner shown and described in UnitedStates Patent No. 1,067,427, issued under date July 15, 1913.

The principal object of the present invention is to provide incombination with such a window, a cooperating lifting device for thewindow sash, whereby a very slight lift is required in order to raisethe window sash so that it will swing upon its hinges.

In order that others may understand my invention, I have shown oneembodiment thereof in the accompanying sheet of drawings, which I willnow describe.

In the drawings,Figure 1 is a fragmentary, sectional view representing aportion of a window sash and frame, and showing the hinge mounting, theupper part of the figure illustrating the application of my presentinvention thereto; Fig. 2 is a fragmentary plan view of a lifting deviceembodying the invention; and Fig. 3 is a side view of one of the hinges,in the lifted and open position.

In the drawings, 1 designates a window sash, 2 a window frame, and 2 awindow sill. The window sash is hinged to the window frame by means of ahinge 3, having as a part thereof an attaching plate 8*, set at anangle, as shown, and knuckles 3 adapted to be alternately positionedwith corresponding knuckles 3, upon the pintle 3 the knuckles 3 upon thehinge plate 8, bein movable vertically upon the pintle 3 a c istancecorresponding to the distance the window sash moves down into the windowsill 2, as will be readily understood from the drawings and from thepatent before referred to.

The invention proper comprises a window frame plate 4L,mo-unted in theinner face of the window frame, in vertical alinement with the edge ofthe window sash, said plate having a pair of projecting arms or wings,

as 5-5, extended into the window frame, with a supporting pivot pin 6therethrough, upon which is pivotally mounted a lifting lever 7 upon theinner end of which is sus pended a balancing weight 8, within the windowframe casing. Set into the edge of the. Window sash, opposite saidwindow frame plate 4, when the window is closed, is a sash plate 10,having an opening 11 there through, at the upper edge of which, set intothe edge of the window sash, is mounted upon suitable lugs 12, a liftinganti-friction roller ].3, under which bears the lifting end 7 of thelever 7. The window frame plate at has a vertical opening or slot 9therein, which permits the end of the lever 7 to move upwardly thereinin its lifting action. It will be seen that the weight 8, upon thewindow frame end of the lever 7, tends to lift the window sash by reasonof the en gagement of the opposite end of said lever with the roller 13carried by the window sash, and that very little lift is necessary inaddition thereto to lift the window sash sufficiently to clear thewindow sill and permit the window to be swung upon its hinges. When thewindow sash is thus swtuig, it will be understood, of course, that thewindow sash plate 10 moves off the end 7 of the lifting lever 7.

Thus I provide a lifting device for a window sash which must be liftedslightly before it can be swung upon hinges having vertical axes, andwhile I have shown but one embodiment thereof, I am aware that changescan be made therein without departing from the spirit of the invention,and I do not, therefore, limit the invention to the particularembodiment thereof here shown for illustrative purposes, except as I maybe limited by the hereto appended claims.

I claim:

1. In combination with a window frame and window sash of the characterreferred to, a lifting lever pivotally mounted in said window frame,with a weight suspended upon one end thereof and having its opposite endprojected into lifting engagement with the edge of the window sash, andbeing detachable therefrom, whereby to permit said sash to be moved awayfrom the lifting end of said lever, substantially as described.

2. In combination with a window frame and window sash hingedly andadjustably mounted therein, a lifting lever pivotally mounted in saidWindow frame and project 3. In combination, a Window frame, a

sash-hingedly and adjustably mounted in said frame, a lifting elementprojecting from said Window frame into lifting ena ement With saidwindowsash a Wei ht b I 3, b
